Terminal assignment

The terminal MRS assignment parameter is Pr.183. Set Pr.183 to "4" (AU). (This setting is for the E700.) More Details >>

Running frequency, output current

Since the FR-E700 has only one terminal FM, you cannot read two signals simultaneously.Use the optional digital output/additional analog output FR-A7AY.This ... More Details >>

Applicable motors

In addition to the dedicated motor (SF-VR series), the SF-JR series motor with an encoder can be used. You can also use a standard motor by combining it with... More Details >>

Motor wiring length

Up to 50 m. Be sure to connect the encoder cables in parallel and use the thicker cable gauge. You can extend this distance up to 100 m by using the long dis... More Details >>

What functions are added by upgrading?

The following functions are added by upgrading: - Slip compensation function- Serial communication function- Frequency jump- 15-speed operation- Zero current... More Details >>

Carrier frequency of low-noise series

The carrier frequency is initially set to 7 kHz. (When Pr.10 is set to "---", you can set or change the setting using Pr.72.) Raising the carrier frequency r... More Details >>

Harmonic suppression guidelines for power supply

Since the high power factor converter uses the self-excitation three-phase bridge (voltage type PWM control) circuit configuration (type), the conversion coe... More Details >>

Combination with existing inverters

Since the existing inverters do not have a terminal to connect to the FR-HC, it cannot be connected to them. Use an inverter compatible with the high power f... More Details >>

Protective functions

Protective functions against the power supply fault, overcurrent, element fault, undervoltage, and transistor thermal fault (inverter protection) are availab... More Details >>

Power supply capacity

Since the input power factor is improved to approximately 1, the power supply capacity can be reduced to 2/3 to 3/4 of an inverter without a power factor imp... More Details >>
